Reports from New York show that the first major wave of warblers has arrived there, with 20 species from Central Park today (Tuesday). WSW winds tonight and for the rest of the week should move many of these birds into Massachusetts. It may be a stretch for them to make it up here in one night, but if not tomorrow, I suspect Thursday should see the arrival of some much-awaited species. I'm by no means an expert prognosticator, but for the first time in many days, the radar looks very promising (see: https://goo.gl/v2cEk9 ).
A post yesterday from a birder who, in his own words, "never quite figured out how to take advantage of radar," prompts me to post a few resources on the subject. Radar is a powerful tool for understanding migration for birders and scientists, and it is worth taking some time to learn how it works.
Birdcast ( http://birdcast.info/ ) is by far the simplest way of predicting migration on a regional scale. But looking at the radar visualizations themselves can provide more specific information, like how migrants are interacting with a weather front, when migrants are stopping at coastal sites and when they are continuing past the coast, and just general points of interest like how high and how fast migrants are flying. David LaPuma has a classic video tutorial on the subject: https://vimeo.com/2020985?pg=embed&sec=2020985 Some FAQ are posted at: http://www.woodcreeper.com/radar-migration-faq/
I still have a great deal to learn about how radar works and welcome discussions about it from folks that can teach me about it (especially if I get anything wrong in my above-mentioned blog posts). That said, I'm posting about it because it's an endlessly fascinating topic, and at least merits annual mention on any birding listserv.
Good birding- get out there tomorrow and see what's up! Will Freedberg Belmont, for better or for worse, Williamfreedberg at gmail.com
